Class 9999 – Mechanical Interlocks
Mechanical Interlock
General: Type S contactors or starters can be mechanically-interlocked so that only one device will be
energized at a time. The mechanical interlock is an interference (non-jamming) type, locking at the
beginning of the stroke of any starter or contactor.
Type SM1
Type S Sizes 00, 0, 1 and 2 – The mechanical interlock is mounted on the underside of the reversing
baseplate. Two pins extend from the mechanical interlock through openings in the baseplate and
engage the contact carrier of each contactor. Two styles of mechanical interlocks are used: one version
for three-pole contactors, a different version for four- or five-pole contactors. When adding a power
pole to the left-hand side of an existing Size 0, 1, or 2 three-pole reversing contactor, a new
mechanical interlock must also be installed. When added to the right-hand side only, the power
pole will not be mechanically-interlocked with the left-hand contactor.
Type S Sizes 3 and 4 – The mechanical interlock is separate from the mounting pan on Sizes 3 and 4.
Cams on the mechanical interlocks are operated by the contact carrier of each contactor. The
mechanical interlock is attached to the underside of the two contactor baseplates on Sizes 3 and 4.
Mechanical Interlock for Two Contactors
The following mechanical interlock kits can be used to interlock 2-5 pole contactors. Mechanical
interlocks for horizontal and vertical arrangement are listed in various pole arrangements.
